UNITED STATES PATENT OFFICE GUN SIGHT Alfred M. Pasquarella, near NewBedford, Pa.

Application October 5, 1950, Serial No. 188,525

1 Claim. 1

This invention relates to a gun sight and more particularly to a gunsight for application to a service revolver to enable the same to beused as a, target pistol.

The principal .object of the invention is the provision of a simple,easily attached and adjusted gun sight for a service revolver.

A further object of the invention is the provision of a gun sight for arevolver which may be attached to the revolver without machining away aportion of the frame or other part of the revolver.

A still further object of the invention is the provision of a gun sightthat provides vertical and horizontal adjustment to enable the equippedgun to be readily zeroed in on a target.

The gun sight disclosed herein provides a simple and efiicient means forconverting a revolver for use as a target pistol and without theheretofore believed necessary machining away of portions of the frame ofthe gun and the installation of complicated gun sight mechanism in themachined portions.

As known in the art, the rear sights on revolvers are machined in theupper longitudinal portion of the frame near the hammer of the gun andare so formed as to be effective only at a relatively close range.

In order to use the gun for target shooting practice it has heretoforebeen necessary to machine away a portion of the frame and form atransversely extending dovetailed channel in the frame of the gun andinstall the gun sight mechanism in the channel. This has necessitated atime consuming operation which is relatively expensive. The presentinvention eliminates the necessity of altering the gun in any manner asthe same may be positioned on the gun and automatically provides therear gun sight in the proper location and elevation to enable the gun tobe used as a target pistol in target practice.

With the foregoing and other objects in view which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being the intention to cover all changes andmodifications of the example of the invention herein disclosedforpurposes of the disclosure, which do not constitute departures from thespirit and scope of the invention,

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a side view of a portion of a service revolver showing thegun sight in position thereon.

Figure 2 is a rear view taken on line 2-2 of Figure 1.

Figure 3 is an enlarged top plan view of the gun sight.

Figure 4 is a front view taken on line 4-4 of Figure 3.

Figure 5 is a side view taken on line 5--5 of Figure 4.

Figure 6 is a vertical section taken on line 6-6 of Figure 5.

By referring to the drawings and Figures 1 and 2 in particular it willbe seen that a revolver has been illustrated including a frame In,stocks barrel I2 and cylinder I3. The trigger is indicated by thenumeral l4 and the hammer by the numeral 5. The gun sight comprising theinvention is illustrated as being positioned on the uppermost portion ofthe frame l0 above and forward of the hammer l5. In Figures 1 and 2 ofthe drawings the body member of the gun sight is indicated by thenumeral 6.

By referring to Figures 3, 4 and 5 of the drawings it will be seen thatthe body member 5 has depending end sections forming with the bodymember I'G an inverted U-shaped device of a width sufiicient to span theframe ID of the gun as shown in Figure 2 of the drawings. The dependingend sections |'l-|| are positioned on the opposite sides of the frame Inand are provided with drilled and tapped openings |8-|8 in which setscrews Ill-l9 are positioned. The length of the depending end sectionsI1 is greater than one-half of the overall height of the body member IS.The set screws l9-l9 are adapted to be turned inwardly so as to forciblyengage the sides of the frame In of the gun and thereby position thebody member I6 on the gun. The body member l6 has a transverselyextending slot 20 in its uppermost portion. The slot 20 is relativelynarrow and is adapted to receive a notched plate 2|, the notch thereinbeing indicated by the numeral 22.

Transversely spaced drilled and tapped openings 2323 are provided in thebody member l6 of the gun sight and set screws 24-24 are positionedtherein so that their innermost ends project into the slot 20 forengagement against one side of the plate 2| therein. It will thus beseen that the plate 2| may be adjustably positioned in the slot 20 byloosening the set screws 24-24, positioning the plate 2| in desiredposition and re-tightening the set screws 24-24. In the event theelevation of the notched plate 2| is necessary, the same may bepositioned in spaced relation to the bottom of the slot 20 oralternately a notched plate 2| of greater height may be substituted. Ineither event, the gun sight provides for both horizontal and verticaladjustment to enable the sight to be adjusted to the actual projectilepath of the gun and with respect to a target whereby the gun may bezeroed in on the target.

In Figure 6 of the drawings the notched plate 2| is shown in plan viewresting on the bottom of the slot 20 in the body member l6 of the gunsight. It will be observed that in the event it is necessary to lowerthe notched plate 2|, the bottom of the plate 2| may be cut offappropriately or, alternately, the bottom of the body member l6 betweenthe depending ends I! may be cutaway slightly to adapt the gun sight toa particular gun frame.

It will thus be seen that the gun sight disclosed herein meets theseveral objects of the invention and provides an effective rear gunsight for a service revolver enabling the same to be used as a targetpistol. A further advantage ofthe gun sight disclosed herein as comparedwith gun sights as known in the art is found in positioning the gunsight over the gun sight ordinarily machined in the frame ll) of thegun. In Figure 2 of the drawings it will be seen that the notch 22 inthe plate 2| is directly above the notch in the frame of the gun thusproviding a definite vertical guide enabling the gun to be alignedvertically with respect to the target which aids materially in accurateshooting. The notched gun sight in the frame I is indicated in Figure 2by the numeral 25.

It will thus be seen that the several objects of A rear gun sight for arevolver to enable the same to be used as a target pistol, the said reargun sight comprising a short inverted U-shaped body member, the arms ofthe said inverted U- shaped body member engaging the opposite sides ofthe frame of the said gun, a slot formed in the uppermost portion of thesaid inverted U- shaped body member so as to lie transversely of saidgun and a notched plate disposed in said slot, drilled and tappedopenings in the arms of the inverted U-shaped body member and set screwsin the said drilled and tapped openings for frictional engagement withthe opposite sides of the said frame of the gun, and secondary drilledand tapped openings in the transverse portion of the inverted U-shapedbody member and at right angles to and communicating with the inventionhave been met by the gun sight disclosed herein.

Having thus described my invention, what I claim is:

the slot therein, set screws in the said secondary drilled and. tappedopenings and engaging the said notched plate;
